Many things are spoken out loud, but be careful of those words that you whisper to yourself. You have the ability to uplift yourself or condemn yourself. If your thoughts are depressingly running across your mind. You need to make adjustments and change your way of thinking.
Our every action has consequences. Thoughts have consequences. Since actions start from thoughts I guess I can say technically that thoughts in general have consequences. In our thoughts we make dreams. So if I think I can do it, then my actions will be "I CAN" and I am able to do it. So the result or the consequence will be "I did it!".
